I think failed casino strategies are based on false assumptions about how probability works. For example, the gambler's fallacy is the mistaken belief that previous events can influence the outcome of future events, even though each event is independent. Other strategies may rely on betting progressions, where a player increases or decreases their bet size after a win or loss. While these progressions may seem to make sense in theory, they do not alter the basic odds of the game or protect the player from long losing streaks.
